Major drop in download speed

[#1]

To use a Yorkshire phrase: Summats not reight, there. Try again in an hour or so - that failed, for some reason.

Here is the BT diag

Better - but not by much.

Hi Alastair,

From what I can see the only work the engineer logged that they'd carried out was replace the master socket faceplate. 

As your phone line's improved, I've reset your line to remove the ~2mbps speed restriction which was automatically placed by the equipment at the exchange, due to the fault you had. 

The line reset should go through within 24 hours, let me know how it goes.

@Gandalf 

Better, SNR back to 6db.

Hopefully thats it.

[#6]

Hi guys, the fault on the phone was fixed. line reset and broadband was working at 18806kbps.

The line dropped yesterday morning and re synced at 16800kbps and snr 9db.

This morning the line dropped twice and resynced at 15000kbps and snr 12db.

I think there is still a fault somewhere on the line.

@Gandalf  Can you reset the DLM again?

Hi Alastair,

I'm sorry to see you're still having issues. From what I can see your speed's not restricted but I can see the SNRM target is 12dB and your connection's been dropping. Line tests are showing an issue with the lead-in wiring into your property. 

Are you free for an engineer to take another stab at the problem?

[#10]

Hi @Gandalf thanks for the response.

What is the lead-in wiring?

Shouldn't the fault have been detected by the engineer that was out?

I am free on Tuesday and wednesday next week, morning or afternoon.

[#11]

Hi Alastair,

The lead-in wiring is the cable from the line outside to your master socket. Maybe depends whether the engineer thought it'd affect your phone service as well, because the previous fault was raised as a phone fault to look at the noise.

I've arranged a broadband engineer this time around. The appointment's booked for Wednesday 2nd November 1pm to 6pm.

Let us know how it goes.

[#12]

Hi @Gandalf 

The engineer was out tested the line fitted a filtered faceplate. The router first synced back at 12db at 14200, there was a powercut about and hour later for about 46 mins, the line synced at 20200 and 3db.

About 3am the line dropped and synced at 14800 and 12db back to what it was before.
Can you test the line again?

Thanks

Alastair

Hi there Alastair, 

I've just tested the line, and it's not showing any obvious issues, logs do show that the connection is dropping again unfortunately:<img src="http://visualradius.plus.net/visualradius/generated/image16674767143459.png"/><div style="clear:both;"></div>

If a number of those were due to power cuts I'd give it a few days before we review the logs again and see if we need to take any further action.

Hi @adamwalker 

The line has been stable now for 77 hours, the modem is still synced at 14800kbps but its still at 12 db SNRM.

Gandalf said there was a fault on the lead in wiring, the engineer never touched any thing outside.
The modem synced alot faster at a lower SRNM of 3db after the powercut then dropped and synced at 12db (must have been at 2100 according to your RADIUS).

[#15]

@Gandalf can you help?
